This document specifies requirements for using identifiers in distributed ledgers including blockchains. These requirements supplement those of ISO 8000-115.
The following are within the scope of this document:
— requirements for each identifier in distributed ledgers including blockchains, where the ledger enables supply chains to exchange transaction data;
— requirements for the off‑ledger data set that is referenced by an identifier in a distributed ledger;
— off-ledger data sets that consist only of property-value tuples, where each tuple is the result of semantic encoding.
The following are outside the scope of this document:
— requirements for implementing distributed ledger technology including blockchains;
— requirements for technology to ensure immutability of data sets;
— requirements for the processes of creating identifiers;
— requirements for the processes of creating the content of off‑ledger data sets;
— requirements for the processes of creating immutable data sets.
